Chromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.
Most of the world's known chromite occurs in two deposits: the Bushveld Complex in South Africa and the Great Dyke in Zimbabwe. The chrome ore resource in Zimbabwe is categorized as world class, and considerable value adding takes place as ore is processed into Ferro-chrome alloys before export.
There is scope to go further in value addition, as all the inputs for stainless steel production are available locally and input costs for fabrication are competitive. Although there is a high demand for raw chrome in international markets, the country has adopted the policy not to export raw chrome exports.
Crushing is the first stage in the mineral processing operation.This process step prepares the ore for further grinding or for feeding directly to the classification or concentration separation stages. Chromium mineral crushing operation can be operated in three stages according production requirements: primary crushing, secondary crushing and tertiary crushing operation.
After extraction from quarry or mines, the chromium minerals will be fed into the crushing plant for size reduction. Large material usually is reduced in size by either a jaw crusher or a gyratory crusher.In some operations impact crushers are used for primary crushing, but they may have a slightly higher cost per ton.
Secondary and tertiary crushing, if necessary, will be applied for reducingthe material to a desired finer product size. Usually,impact crusher and cone crushersare the most common choice crusher machines, but in recent years impact crushersare more widely used.
According to production requirements, different types of crushing plant will be applied in the chromium mineral crushing applications for producing fine particle size. SBM developed complete range of chromium mineral crushing plant in Zimbabwe, including jaw crushers, impact crusher, cone crusher, gyratory crusher etc., which are available in stationary, portable and mobile applications. Our crushing solutions offer you true mobility, high capacity, quality end products and reliable operation. Here are the detailed informations about some popular crushing plant.
Jaw crushers are large stationary crushers and are available in a variety of models. They are generally fairly simple in design, making them easy to maintain or repair.
Impact crushers are based upon several decades of experience with the impact method. We offer a complete range of impact crushers for stationary, semi-mobile fully mobile applications in both primary and secondary crushing.
Cone crusher is a stationary crusher. These crushers are hydraulic pressure crushers designed to crush a high ratio for high productivity. Cone crushers are ideal for secondary and fine crushing.
Nowadays, mobile crushing equipment is widely applied in mining and quarrying operations, especially mobile jaw crusher, which is mainly used for primary size reduction. In chromite mining operation, mobile chromite jaw crusher equipment is the integral machine; it is welcomed in chromium crushing applications in Zimbabwe.
Mobile jaw crushers represent the highest technical and manufacturing knowledge. The innovative design offers owners the truly mobility and flexibility, excellent reliability and numerous mounting possibilities. Where cost-efficient primary reduction of hard, abrasive materials is concerned, the mobile jaw crusher will be best choice. Please chat online with us for more information.
